RESILIENT-SHAFT-BEARING-RETAINING DEVICE.-

Application filed Butcher 27, 1920. Serial to. 419,9-i5.

' To all whom it may concern:

Be it known that I, Erreur. BUoArrI, a subject of the King of Italyresiding at Molsheim, Alsace, in the y public `of France, have inventedcertain new and useful Improvements in Resilient-Shaft-Bearing-Retaining Devices; and l do hereby declare the following to be afull, clear,

and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had'to the accompanyin drawings, and to letters orfigures of re erence marked thereon, .which form a part of thisspecification.

ln the Umted States patent specification No. 1143887, l have describedmeans tor obviating the drawbacks to an overhan 'ng fly wheel which iskeyed to 'the end o the y engine shaft and forms the casing tor theclutch for transmittin the rotation of the said shaft to the Car anshaft.

Such means consists in rolonging the crank or en 'ne shaft beyond) andin rear ont the fl Whee by means of a length oi a hollow s aft turningin a bearing mounted on a projecting arm or a bracket oi the motorcasing, the Cardan shaft being arranged within the said hollow shaft.

As stated in the said Specilication, the said bearing may, for somereason or other get out oi axis with respect to the axis ot the engineshait, which causes the hollow shaft to bend or twist at each turn ofthe which the out-of-axis bearing obli es it to take. lin suchcircumstances the y wheel will vibrate and in the end the hollow shaltlarm or racket by the pressure of rings which mag be of leather.

The fo owing description in regard to the accompanyin drawing, given byway of example will exp ain the particular arrangement.,

engine shaft so as to attain the position Fig. 1 shows a horizontalsection of the im roved mounting of the bearing.

ig. 2 is a detail view in section of a resilient ring.

The hollow shaft 1*, which is fixed, by means of bolts for example, tothe ily wheel d which is keyed to the end of the crank shaft b turningin `bearing t', with or with- Aout interposed ball bearings u, thebearin being maintained at the end of the arm a of the casing a by anelastic or resilient device. To this end, the bearing may comprise aring t ada ted to accommodate the ball bearings and aving externally adat, circular flange or projection t2, retained by pressure between twodiscs v of leather or other material, the pressure being produced bymeans of a plate e which is, for exam le attached by means of screws rwto the en ci the arm or bracket a. lt is advantageous to provide in thebottom of the seatings of the discs v the resilient rings ai which maybe of metal and have a section in the form of an arc of a circle orother curve in order to be capable of flattening by means of theirresiliency, which resilient rings transmit to the leather discs thepressure exerted by the plate e.

lt will be conceived that owing to this ressure mounting, the bearingcan adjust itself to the axis of the motor in the case where, for somereason, itfis diverted thus attenuating and even suppressing vibrationof the Hy wh'eel.'

llt will be understood that the mode or carrying out the invention isnot'limited to t e arrangement described and that the resilient oryielding connection can be effected in any convenient manner without dearting from the spirit of the invention.

aving thus described the nature of the said invention and the best meansi know of carrying the same into practical edect, l
